IPC: F23N3/06
Filed: 1916-12-12
Abstract: 107,528. Wiley, E. C. Dec. 12, 1916. Air supply and draught, regulating.-In solidfuel furnaces, especially in those of steam-generators used in heating-systems, the draught is controlled by a device fitted at the rear of the boiler &c and formed with air-supply ducts which are regulated, preferably automatically, by a single valve, so as to affect the air supply to various parts of the furnace. In the device shown, the air is supplied to the ash-pit, to the combustion space, and to the chimney flue, or to the ash-pit and either of the two last-mentioned parts. Fig. 3 shows a casting 7 with ducts 13, 20, 28 controlled by a segmental valve 34 which is pivoted on arms 30, and is moved by a pressure-actuated system of levers, so that, after the fire in the boiler has been lighted up, the rising steam pressure first cuts off the air passage 13 to the ash-pit, and then, to check undesirable rises in the steam pressure, admits air to the check-draught passage 28, 23, and the chimney 5, and then, to check excessive rises in the steam pressure, admits air to the ducts 20, 17 and to the combustion chamber 4 at a point and in quantities such as to cool the fire and the water spaces surrounding it. In modifications, (1) an upward extension of the valve 34 is fitted to cut off the check-draught passage as the passage 20 is opened, (2) the passage 20 to the fire-place, or the passage 28 to the chimney is omitted, (3) tha valves 34 may be replaced by flat sliding valves. The passage 17 is made oblique, as shown, to protect the damper and casting 7 from the direct radiation of the fire.

Title: Long-playing sound record and means for producing the same
IPC: G11B25/00
Filed: 1927-07-07
Abstract: 303,759. Sykes, A. F. July 7, 1927. Feed-motions; sound boxes, supporting; tool.-Hill-and-dale records are cut with a V or truncated V cutter by a non-resonant electrical recording device influenced by a non-resonant microphone and so loaded or damped as to avoid distortion at resonant frequencies due to the resistance of the wax record blank to the cutting. Provision is made for varying the pitch of the record grooves at increased amplitudes. and also if desired, the depth of cut, whereby longer records may be provided on the disc blank. The stylus is of V-section. with the point, rounded or flattened, or may have parallel sides with a. V-point, or is formed with the angle embraced by the sides greater near the point to reduce " bead " effect on the record groove and avoid shouldering of the stylus. As shown, the recorder 4, Fig. 2, which may be that described in Specification 263,502, is mounted for angular adjustment in a pivoted bracket 5 and traversed across the record blank on the turntable 3 by a link 9 connected through a flexible member 40, Fig. 3, with a carriage 36 traversed by a feed screw 27 driven by gearing 32, 33 and belt 34 from a motor controlled by a governor 49, Fig. 5. The governor brake 46 can be, initially adjusted by a screw 45 and is further adjustable by a, Bowden wire connection 23, Figs. 2, 3 and 5, to a pivoted control handle 22, winch is also connected by a wire 18 to an arm 16 fixed on a screw 14 for initially adjusting the pivot of the bracket 14 for the normal depth of cut. The operator by observing the score in advance of the recording is able by manipulation of the handle 22 to adjust the governor brake 46 so as to vary the pitch of the grooves for one or two revolutions at the louder passages and through the wire 18 to adjust simultaneously the depth of cut. Another method of adjusting the depth of cut consists in mounting the turntable so that it can be tilted slightly whereby a stylus associated with a floating weight and slide ball can penetrate, the record more or less. Specification 160,223 describes suitable recording devices and microphones for masking the distortion effects of the wax resistance. Specification 158,137 is referred to. The Provisional Specification also describes the use of cones connected by a belt on a pair of relatively adjustable friction wheels for effecting the variable traverse transmission.

Abstract: 748,510. Drying clothes. HOWE, W. L., and NORTH WESTERN GAS BOARD. June 24, 1954 [June 30, 1953], No. 18138/53. Class 34(2). [Also in Group VIII] A combined washing and drying machine has a single rotatable drum 1 for containing the clothes being treated during washing and dryirg, a casing 2 enclosing the drum for holding water for washing, a heating chamber 8 with means 17 for heating the casing and the air in the chamber, a communication between the casing and the heating chamber which is sealed by the water in the casing during washing but allows hot air or gas to pass to the casing for drying, and means for drawing off steam during washing and for drawing hot air or gas through the drum for drying. The heating means for the chamber 8 comprises oil or gas burners 17 or electric or steam heaters. The chamber 8 is connected through a port 9, inverted U-duct 7 and a port 10 with the casing 2. During drying, hot air from the chamber 8 is drawn through the drum 1 by a fan 5 connected to the casing 2 through a duct 11 and port 12. During washing, water in the casing 2 blocks communication through the duct 7 and the fan 5 draws steam through the duct 11, a door 13 being opened to allow free entry of air to the duct 11. The fan 5 discharges through a nozzle 14 of an ejector 15 and this draws the waste gases from the burner 17 through a port 18 and duct 19. The gas supply to the burner 17 is controlled by a thermostat 23 and is cut off automatically in the event of supply failure by means of a magnetic valve 24 connected with a drive motor 4. The motor 4 drives the fan 5, and the drum 1 and a shaft 6 for a wringer or ironer through a gear box 3. A clutch in the gear box is automatically disengaged and the drum 1 stopped if a door 30 is opened. The burner 17 may be rotatable so as to heat the casing 2 during washing and to supply heat to the bottom of the duct during drying. A cold water spray pipe 33 may be used to remove scum deposits from the duct 7.

Title: Electro-optical display cell

Filed: 1972-04-19
Abstract: 1387317 Modulating light LICENTIA PATENT-VERWALTUNGS-GmbH 19 April 1972 [21 April 1971] 18167/72 Heading H4F In a electro-optic cell, material in the nematic phase and having negative dielectric anisotropy is disposed between two electrods so as to form a uniaxial layer (homeotropic alignment) with the unique exis substantially normal to the electrode surfaces. On application of a D.C. or A.C. potential difference above a threshold level between the electrode, the nematic layer, while remaining uniaxial, has its axis tilted with respect to the original axis (tilting of the molecular long axes from the 90 degree alignment relative to the electrodes), so that whereas the layer formerly appeared isotopic to plane polarized light at normal incidence, it becomes birefringent. Further increase of the applied potential difference leads to dynamic scattering, but this may be counteracted by increasing the frequency of the potential difference. To modulate white or monochromatic light, the cell may be disposed between crossed, parallel or intermediate positioned polarizers, using the variation in birefringence. Alternatively a pleochroic dye may be added to the nematic layer for variable light absorption thereby if the emergent light is passed through an analyser, the colour thereof is further modulated. As particularly described, the electrodes are both transparent, or one transparent and one reflective. The transparent electrodes are tin dioxide coated glass, prepared by heating to close to the melting point of the glass and subsequent cooling. The electrodes may be subdivided, e.g. X and Y address lines on opposite plates, for selective addressing. Since the threshold potential difference V schw , e.g. 10 V., is more than half the potential difference V s  at which the maximum effect is obtained (V s -V schw  is approximately IV) lines may be enrgized at V s /2 without cross-talk. The water content of the nematic layer is preferably less than 0.1%.
